MUSICAL BOX.

BCIFICITION forming part of Letters Patent No. 346,757,61ated August 3,1886.

Application tiled October 10,1885. Serial No. 179,504. (No model.)

To @ZZ when?, it may concern:

Be it known that I, PAUL LocnMANN, a subject ol" the King of Prussia,residing at Gohlis, near Iieipsic, in the Kingdom of Saxony, GermanEmpire, have invented new and useful. Improvements in Musical Boxes, ofwhich the ibllowing is a specification.

rilhe invention forming the object ol' the p resent application Al'orLetters Patent consists et' an improved construction of musical box ormechanical musical instrument.

In my improved music-box I employ a plate provided with pegs or pins anda two-part comb, which pins or pegs are so arranged that those pins orpegs ot' o ne half of the plate engage with the corresponding half orpart of the comb, and those of the other half or part of the plate avoidthe aforesaid half or part of the comb and engage with the other part orhalt ol` the comb.

My invention is shown in the annexed drawings.

Figure i is a vertical section of the musical box, and Fig. 2 a view ol'the cover with the pin-plate '.tixed thereupon.

Upon the steel axle u, placed centrally on the bottom of the ease g, thesoundingvcomb s, divided into two parts, is placed, so that the same canbe set in rotary motion by the driving-whcel r by means ol1 a springplaced in the box l1.. A note peg-plate, p, is employed, which is simplyplaced upon the inner side ot' the lid d, which folds back by means ofthe hinge c. rlhe pegs are inserted in niches according to the notes ol'the piece to be played, so that the half ofthe plate-circle only can bereached by the corresponding hall' oi" the comb, while the pegs of theother half of the circle-plate avoid the teeth of that comb andcorrespond to those of the other comb.

In the drawings, Fig. l shows the lel't side ofthe comb struck by thevarious pegs corresponding to it. rIhe pegs visible between the teeth otthe comb ot' the second half of the plate will come in contact with theteeth of the other comb on the completion of a halfturn of thepeg-plate. The number of combs may be increased, say, to iour or eightby placing them radially around. the axis at dit'- i'erent positionswith .regard to the 'fixed pegplate.

rEhe music can be stopped immediately at any time by raising the lid,andbe altered by replacing the peg-plate by another.

It is obvious that the combs might be fixed and the pin-plate arrangedto rotate without departing from the principle or" this invention.

I am aware that it is not new to employa revolving disk provided withradial. grooves containing teeth adapted to engage with teeth of astationary or lixed comb; also to employ a Iixed or stationary diskhaving perforations adapted to act-nate key-levers having pins engagingwith the perl'orations ofsaid levers.

Having now particularly described and ascertained the nature of my saidinvention and in What manner the same is to be performed, I declare thatwhat I claim isl. The musical-box mechanism having the plate providedwith pegs or pins and the twopart comb, the said pins or pegs being` soarranged that those of one halt' ot the plate engage with thecorresponding part or halt1 ot' the comb, and those pins or pegs of theother half of said plate avoid the said hal l' or part of the comb andengage with the other part or half of the comb, substantially as andl'or the purpose specified.

2. In a musical-box mechanism, the plate having the pegs or pins and thetwo-part comb mounted upon a support having a central sleeve or hubinserted upon a sha't or spindle, the lower or one end ol' said sleeveor hub being geared to a driving-spring, and a bellows or blower,substantially as and for the purpose speeited.

3. In a musical-box mechanism, the fixed plate having pendent pegs orpins inserted in niches therein, in combination with the revolvingtwo-part comb, the said pins or pegs being so arranged that those ot'one half ol' the plate engage with the corresponding part or half of theeomb,and those ofthe other halt or part of the plate avoid the saidhali'or part of the comb and engage with the other hall' or part of thecomb, substantially as and l'or the purpose set forth.

In testimony whereofl have signed my name to this specification in thepresence ottwo subscribing witnesses.
